Split the pulpit mic signal?

Post by craiggsmith »

Another option proposed was to split the pulpit mic signal and send a feed directly to the computer using a USB audio adapter such as the following. But wouldn't the phantom power that it would be connected to fry the adapter?

Maybe. And it depends on how you split it. A better unit can block the phantom power. Either way, you're risking ground loops. The record out jack is transformer isolated. Also, splitting the signal may reduce the volume by 3dB or so.

Sorry, I'm just talking about a cheap passive direct-wired splitter. I've updated the original post with a link. Yes it would reduce the volume but that's not an issue. Just wondering if this would work. I don't know if the phantom voltage level is a full 48 but I wouldn't think it could handle much if any; best case I'd think it would be overloaded.

I'm getting pushback on running a cable from the record out jack, which is 20 feet or so away, plus we'd have to buy an adapter/attenuator and cables. I'm really surprised that jack is transformer isolated.

In general anything better would cost a lot more, although apparently we could use a crab box to isolate the phantom power. Right now I'm leaning towards a cheap lavalier mic like those that have been posted in other threads. But a feed from the pulpit mic would be the best quality.

It would reduce the volume of the sound system, not just in the feed. There's also zero isolation, so if that adapter does something like wiring the mic as unbalanced, the sound system may not be happy.

Reading some of the questions, I'm not getting a warm fuzzy. It doesn't seem to work in the conditions I'd think it was meant for.

The transformer on on the back of the plate. So, it really doesn't matter what's gong on in the rack.

I'm not sure how you'd do that. The crab box is designed to take line level down to mic level. You're not going to be able to feed in mic level and get mic level out. What you could do is take the record out, run it though the crab, and then adapt from XLR to whatever your computer takes.

Splitting the pulpit microphone signal is also going to cause the computerized chapel sound system to try and compensate with unpredictable results.
